not compatible with 800x600 resolution

[CowMilk]

is there any way to make my site compatible with every resolution, i'm currently having problems with 800x600 only. some side are overlapping especially the left side with the fixed ads and shoutbox.

Well your shoutbox is 250 pixels wide so make your #left div at least 250px wide. Then change the left margin of your #content div to at least 250px that should stop the overlapping.
